Uhereye kumikorere yacyo, iyungurura ivumbi rifite akayunguruzo keza. Dufashe impuzandengo yubunini bwa 0.5 microne yifu nkurugero, imikorere yo kuyungurura irashobora kugera kuri 99,99%.
Ntabwo aribyo gusa, ikoreshwa ryiyungurura rishobora no kuzigama ikirere gikonje; uburyo bwo kwishyiriraho umuyaga wa filteri ya silinderi nayo izarushaho kuba siyanse kugirango ihure nikibazo nyacyo cyabakoresha batandukanye.
